You will find indications for the
relationship between load capacity and
temperature on the surface as well as
for the dimensioning of the resistor at
short term load in chapter “Technical
Details”, pages T103E-T108E.

Application
As ballast, limiting, filter or series
resistors etc. for integration into devices
and customised units. Our type series
F.B.. is very well applicable in switch
cabinets. We fix the threaded rod for you
in a space-saving way. Efficient use in
your manufacturing systems.

We provide M3 screw connections for
construction sizes with diameters D=16
and M4 with D=24/35/45 M5 with D=65.
Also fast-on connections (6,3x0,8) are
available for sizes with D=24/35/45.
For sizes with D=16 the soldering
connections can also be used as fast-on
connections (4,8x0,5).

Hints for the versions with adjustable clips
For the cemented fixed resistors with adjustable clip we decrease the available
maximum ohmic value. Since otherwise while adjusting the clip, the danger of
breaking the wire would be too large because of too thin wires. The adjustable
clip may only be adjusted in a condition free of voltage and after sufficient
loosening and cooling. All the adjustable clips of our fixed resistors in tubular
version are equipped with silver contacts. When selecting please consider that
the maximum surface temperature (ST) should not exceed 300°C.
Please consider as well that the resistance value may be reduced with versions
where several adjustable clips are combined, especially in the lower range of
ohmic values and with short tube lengths. In that case we have to select a
higher total ohmic value.

Example of dimensioning and selection of a specific unit:
Adjustable power resistor for mounting into a switch cabinet with 2 additional taps:
continuous dissipation 150 W; resistance value 100 ; rating 110 V DC, mounting
by threaded rod on mounting plate, adjustable resistance taps by 2 adjustable clips,
connection at fast-on clips,
Selected:
FZB 200 x 35 S2T – 100 with continuous dissipation 150 W
Alternatively: FZB 160 x 45 S2T – 100 (continuous dissipation also 150W)
FZB 200x35
